P1: He ngohengohe rawa te whitiki, ā, ka totoro haere i te roanga o te wā, ka whaiti te whānui, ka turuturu te paru ki roto i te awa whāngai. He aha te otinga?

Ānite:Mā te hangarau whakamomona motuhake o te pahu ka huri i ngā ngota PP hei mekameka ngota copolymer, ka nui ake te pumau i ngā mekameka ngota kotahi noa. Mē te taumahatanga 1%, ko te kaha kume he ≥10N ia mirimita tapawha, ā, he tino ātete ki te totoro me te whakarerekētanga.

Q2: I ngā āhuatanga hotoke i raro i te kore o te pāmahana, ka pakari te whitiki, ka pakarukaru, ka ngawari te ngatata, ā, ka pakaru ngā hononga. Me pēhea te whakatika i tēnei?

Ānite:Ka tino whakahaerehia e mātou te modulus rapa i roto i te awhe 800-1000 MPa — te matapihi pakari tino pai mō ngā rauemi PP. Ko te tikanga ka mau tonu te whitiki i te kaha pānga ≥85% ahakoa i te -25°C. Ka noho ngāwari tonu, kāore e pakari, me te ātete pai ki te ngenge. Whakaarohia he rite ki te rapa potae hotoke kounga teitei — ka piko, kāore e whati, ahakoa i te hukapapa nui, ā, ka noho pūmau ngā hononga.

Q3: Kei te hē tonu te ara o te whitiki. Kei te whakatikatika tonu mātou i ngā roera engari kāore e noho tika. Me aha?

Ānite: Ko te take o te hē o te whakatakotoranga he mātotoru kore taurite, he matotoru kore taurite, me te ahotea ā-roto kua hangaia. Ka whakamahia e mātou he rapa parakore 100% - kāore he hurihanga anō, kāore he rauemi kua whakahokia mai - kia rite te mātotoru puta noa i te whitiki katoa, me te pupuri i te ātete matotoru ki roto i te ±0.05mm. Hei tāpiri atu ki tēnā, ka tukuna katoatia e tā mātou tukanga totoro pāmahana-pūmau tuarua te ahotea ā-roto, kia taurangi ai te whakahekenga pumau puta noa i te whitiki. Ko te hua? Ka whakatakotoranga tika mai i te rā tuatahi, me te iti o te whakatikatika e hiahiatia ana.

Q4: Ko te hononga/te hononga te wāhi ngoikore rawa atu — ka pakaru tonu. Me pēhea te whakapakari ake?

Ānite:Ka honoa noa ngā mata papatahi e ngā hononga papatahi tuku iho, ā, he iti noa te wāhi here. Ka whakamahia e mātou he tukanga taupatupatu takahanga-ā-matihao — pērā i te raka i ngā maihao tekau — ā, muri iho ka whakamahia he whakarewa honohono pāmahana teitei, pēhanga teitei. Ka eke te kaha kume o te hononga ki te ≥95% o te tinana o te whitiki. Ka tāpirihia hoki e mātou he paparanga polyester ātete-roimata ki te hononga, ka rua te roa o te ora o te ngenge. I roto i te poto, ka roa ake te hononga i te whitiki.

Q5: Ka whakamahia e mātou ngā whitiki ki waho. Ka puta te kirikiri, te ngatata, me te koroheketanga wawe i te pānga o te hihi UV. Me pēhea te whakaroa i te roa o te whakamahinga?

Ānite: Ka whakakotahi mātou i te whitiki me te pūnaha honohono o ngā HALS (Hindered Amine Light Stabilizers) me ngā mea mimiti UV nano-tauine — e whakarato ana i te parenga mata me te tiaki ā-roto. Whai muri i ngā whakamātautau koroheketanga tere o te QUV 3000-haora, ka noho tonu te kaha kume ki te ≥90% me te kore e pakaru te mata. Ahakoa ka pirau ngā whitiki noa i roto i te 1-2 tau, ka mau tonu tō mātou āhua pai mō te 8-10 tau o te ratonga o waho.
